Hot Cold Tickle Water

We went camping for the first time last spring. When we got to the restroom,I realized we have a problem. How is Reese going to get a bath. I finally broke it to her and told her she would have to take a shower. We found one stall, the handicap one that had a shower head that came off the wall. We always used that one, and she never forgot to tell me that she wanted, "hot cold tickle water". We survived another camping trip, and now I hear it when she showers at home also.
